ResumoA single crystal of 17 O enriched α‐glycine was grown by slow evaporation of aqueous solution. 17 O n.m.r. studies of the α‐glycine molecule in single crystalline form revealed five 17 O transitions each consisting of two lines due to inequivalency of the oxygen atoms in the unit cell, with each of these lines revealing a dipolar interaction between the 17 O and the nearest hydrogen atom. The spectral width was found to be of the order of magnitude of MHz and the linewidths of the order of magnitude of 2 kHz.
